The baud rate for Water Sampler communication with the CTD must be
set in both the CTD and in the SBE 33
.
SBE 19, 19

(not 19

), or 49
Set (if programmable) and/or verify the CTD baud rate, and establish CTD
operating parameters:
1.
Connect the CTD directly to the computer
(not through the SBE 33 and
Water Sampler), using the data I/O cable supplied with the CTD.
2.
Double click on
Seaterm.exe
. If this is the first time the program is used,
the setup dialog box may appear:
Select the CTD and the computer COM port for communication with the
CTD. Click OK.

Note:
The SBE 33 is factory-programmed to
command the Water Sampler to
communicate with the CTD at 4800
baud. The setting in the SBE 33 must
match the baud rate programmed in
the CTD.
For the most efficient
operation, keep the baud at 4800
baud if it is feasible for the CTD.
Note:

different terminal program; see
